HORACE E. JONES, OF OARIBOU, MAINE.

MOUTH-PIECE FOR CORNETS.

SPECIFICATION forming part of Letters Patent No. 275,918, dated April 17, 1883.

Application filed October 14, 1882.

To all whom it may concern:

Be it known that I, HORACE E. JONES, of Caribou, in the county of Aroostook and State of Maine, have invented a new and Improved Mouth-Piece for Oornets, of which the following is a full, clear, and exact description.

My invention relates to IDOUihplGCGS used with cornets or similar musical instruments which have no reeds; and the object of the invention is to provide for varying the size of the mouthpiece or air-chamber, so that it may be increased or diminished to suit the requirements of different performers without changing the pitch or tone of the instrument, and thereby to overcome the difiiculty that is often experienced in reaching extreme upper and lower notes.

To these ends my invention consists in the combination with and arrangement of parts whereby the area of the mouth-piece can be increased or diminished, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a longitudinal section ofa mouthpiece with my improvement. Fig. 2 is a crosssection of the same on the line no 00, Fig. 1.

A is the mouth-piece, provided with tube B, of ordinary construction. 0 is an inner tube, fitting snugly in the tube B, and provided at its outer end with a cup, D, that fits closely within the mouth-piece A. On opposite sides of the inner tube, 0, are lugs or projections to a, which are screw-threaded and extend through slots b,formed in the outer tube, B. Upon the outer tube, B, and engaging the threaded lugs a, is a nut, (I, one edge of which is burnished down into an annular groove formed in the tube B, so that the nut is prevented from moving endwise on the tube, and may turn freely. By turning the nut 11 the tube O is moved endwise, and the inner cup, I), being thereby moved in the mouth-piece, the area of the mouth-piece will be increased or diminished, according to the direction in which the nut is (Model) revolved. In that way the size of the mouthpiece may be changed to suit the requirements of any instrument or any performer, or to suit any particular class of music, and at the same time, the length of the tube B not being changed, the pitch or tone of the instrument will not be varied by this adjustment.

In place of using the nut for the adjustment of the inner cup, the latter may be held in place simply by springs, or by friction, and moved by hand by means of its projecting lug or lugs, said lugs beingaccessible to the hand by means of the slots.

This device can be applied to any instrument or" this class; and I do not limit myself to any particular form or shape of the interior movable cup.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent-- 1. The mouth-piece for cornets and similar instruments, provided with an adjustable interior cup and tube, having means extending through an extension of the mouth-piece, and engaging with means on the outside of said extension to enable the adjustment of said interior cup and tube, substantially as shown and described.

2. The combination, with the mouth-piece of acornet having opposite slots, 01), in an exten sion thereof, of the interior tube, O, and cup D, having screw-threaded lugs to, adapted to permitthe adjustment of the said cup and tube by means arranged on the extension of the mouth-piece, and engaging with said lugs for varying the size of the mouth-piece, substan tially as herein shown and described.

3. In cornet mouth-pieces, the combination, with the interior tube, O, and cup D, said tube having screw threaded lugs 0, extending through slots 1) in the extension of the mouthpiece, of the adjusting-nut (l, substantially as shown and described.
